We're dividing 18458183 by 851 
Our goal is to divide 18458183 by 851.

Going ahead to step 1:
If we divide 1 by 851, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 851

Advancing to step 2:
When dividing 18 by 851, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 851

Let's proceed to step 3:
If we divide 184 by 851, we get 0 and a remainder of 184.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 184, we get 184.
Take the next digit (5) from the dividend and append it to 184, then repeat: 1845 / 851

Going ahead to step 4:
851 goes into 1845 2 times with a remainder of 143.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1702 from 1845 and we're left with 143.
Fetch the next digit (8) from the dividend, attach it to 143 and continue: 1438 / 851

Moving on to step 5:
851 goes into 1438 1 times with a remainder of 587.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 851 from 1438 and we're left with 587.
Append the next digit (1) from the dividend to 587 and continue with: 5871 / 851

Let's proceed to step 6:
851 goes into 5871 6 times with a remainder of 765.
Use 6 as the next digit of our solution. 
Result so far: 216.0
Subtracting 5106 from 5871 leaves us with 765.
Fetch the next digit (8) from the dividend, attach it to 765 and continue: 7658 / 851

Advancing to step 7:
When dividing 7658 by 851, we get 8 with a remainder of 850.
The next digit of our result is 8. 
Result so far: 2168.0
Subtract 6808 from 7658 to get 850.
Grab the next digit (3) from the dividend, add it to 850, then carry on: 8503 / 851

Step 8:
851 goes into 8503 9 times with a remainder of 844.
Put 9 as the next digit of the answer. 
Result so far: 21689.0
If we take 7659 away from 8503, we end up with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Moving on to step 9:
When dividing 8440 by 851, we get 9 with a remainder of 781.
Write down 9 as next digit of the result. 
Result so far: 21689.9
Subtracting 7659 from 8440 leaves us with 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Step 10:
If we divide 7810 by 851, we get 9 and a remainder of 151.
Record the quotient 9 as the next digit in the result. 
Result so far: 21689.99
If we take 7659 away from 7810, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

After the division, we end up with 21689.99 and a remainder of 0.151.
